MIXING DEVICE. I

Be it known that I, FORREST A. HEATH, a

' citizen of the United States, and a resident 'son, and v:ed certain new and useful Improvements 1n of the cit of Jersey City, county of Hudtat-e of New Jersey, have mvent- Mixing Devices, of which the following is a specification. This invention relates to mixing dGVlCGS' for-use in combination with carbureting devices for thoroughlymixing, commingling,

agitating or stirring the elements which issue from the'delivery port of a carbureter in order to make it more homogeneous prior to its being introduced into a hydrocarbon or explosive'engine and it particularly relates to a mixing device which comprises a rotatable fan and a relatively coarse screen or wire mesh secured thereto and lying in a plane parallel to the fan. I

This application is a division of my application entitled carbureters, filed May 15, 1909, Serial No. 496,266.

In my co-pending application Serial No. 538,041, filed January 14th, 1910, .a mixing device is shown and described which is similar in many respects to the mixing devices which is shown and described in the present f invention, reference is made to the drawings in which- Figure 1 shows -a horizontal section of the mixing device shown-in Fig. 2 and takenon. the line 1- -1 of the last mentioned figure. Fig. 2 is a vertical -'sectional view of the mixing device taken on the line,2-.-2 of Fig. 1 and also a sectional view of a carbureter which is used in connection therewith.

The carbureting device isv designated by the reference character A. and this has a main air passage A and an atomi zing chamber A opening. therein and is clearly' described in said application above referred to."

the fan and lying in a plane parallel there with. It will be understood that the suction from the engine drawing the gas and air up through the member comprising the fan and screen will cause the fan to rotate the member and the screen will thus operate as an agitator, stirrer or commingling member for the fuel and air, by cutting across (as it does by the wires in the screen or mesh which extend outwardly toward the peripheral portion of the member, say for example, wires corresponding to G andGr shown in Fig. 2 or any of the outwardly extending portions of the wires as for example G, G, Gr or Gr in Fig. 1) the advancing gas and air in a plane substantially at right angles'to the direction in which'the gas and air are moving when they pass the fan. It will furthermore be noted, as from an inspection of the drawings, that theoutwardly extending portions of. the wires constitute comparatively long but narrow and thin portions of materiaL' It is believed that the present construction offers a minimumof resistance to the travel of gas-and air such resistance where a numher 3 wiremcsh (three openings to the inch) 1 s used, being found to be practically negligible. Moreover in order to facilitate rotation of the mixing member E, ball bearings K, K may be provided. In the embodiment of the improved form of mixing device shown in or in combination with a carbureter as disclosed in Fig. 2 the conduit from the carbureter to the engine is preferably widened and the rotatable mixing member is placed in this widened portion.

to merely agitate, commingle or stir and that is, they have a cutting or chopping eflect upon particles of fuel which tend to pass by the fan due to the engagement of the wires with the particles of fuel. In this way the fuel particles become finely divided or broken up and of course a more thorough, homogeneous and uniform mixture of the fuel with the air will necessarily be efl'ected and therefore it will be seen that one of the important features of this invention resides in the fact that there are commingling or cutting elements which extend outwardly towardthe peripheral portion of the cutting member or what would be the same thing cutting elements which extend outwardly or away from the central portion pf a rotatable mixing member comprising a It is obvious that various other forms and modifications may be made without departing from the spirit and scope of my in- I claim as my invention:

1. A mixing device for gas and air comprising a fan and a screen secured thereto and parallel therewith.

2. A mixing device for gas and air comprising a rotatable fan and -a rotatable screen in a plane parallel with the fan and adjacent thereto.

3. A mixing device for gas and air'comprising a fan mounted so as to rotate and a movable member upon the rear side of the fan and adjacent thereto, said member comprising commingling elements spaced from a member comprising a fan and spaced wires extending outwardly from the central portion of the member. a

6. A mixing device for gas and air comprising a fan mounted to rotate and a relatively coarse screen adj acent to the rear face of the fan and also capable of rotation.

7 A mixing device for gas and air comprising a fan having a flange extending around its periphery and an agitator secured .to the flange.

8. A mixing device for gas and air comprising a fan mounted to rotate and havinga flange extending around its periphery and a relatively coarse screen lying in a plane parallel with the fan and secured to the flange upon the rear side of the fan.

\ 9. A mixing device for gas and air comprising a fan mounted to rotate, and having a flange extending around its periphery, and

spaced outwardly extending wires or agltating members parallel with the fan and fitted within the flange upon the rear side of the fan.

10. The combination with a carbureter' and a conduit for gas and air leading therefrom and having a widened portion, of a fan mounted to rotate in the widened portion and having a flange upon its periphery and a screen secured to the flange.

11. A mixer for gaseous fluids arranged to be disposed in the path of gaseous currents to be acted upon, comprising a tubular casing member having at one end a portion having an outwardly extending supporting surface and provided intermediate its ends with a rotatable member wholly supported by anintegral web or spider which is located at the other end of'the casing, said rotatable member comprising fan blades and spaced agitating'or commingling members.

12. As an article of manufacture a mixer for gaseous fluids arranged to be disposed in the path of gaseous currents to be acted upon, comprising a tubular casing having a supporting portion at one end thereof, a spider at the opposite end, a central stud wholly supported by said spider and a rotatable member comprising a fan'or propelhng wheel and outwardly extending disintegratin-g members.
